Cleaup unused variables

Throughout your code you have a lot of commented out items as well as unused variables. I'd suggest going through your module and cleaning up the unused variables as well as any commented out lines of code such as

//    drupal_set_message( 'End date:'.$end_date );
//    drupal_set_message( 'Start '.$start_date.'---- as a Timestamp  '.date('m/d/Y',strtotime($start_date)).' Test date: '.date('m/d/Y',strtotime( '-0 day')) );
